A new study has revealed that men who take testosterone supplements for sexual dysfunction may have a higher risk of blood clots.
The researchers revealed that individuals who took hormone supplements for six months are 64 percent likely to get blood clots in their lungs and legs. Although the risk may become reduced over time, Dr. Carlos Martinez of the Institute for Epidemiology, Statistics and Informatics said that consulting a physician before consuming the supplement is advised.
"This observational study suggests an increased risk of venous thromboembolism soon after the start of testosterone use," the lead author said. He added that the risk becomes low after more than six months of therapeutic consumption. Since the study is only observational, the authors noted that it is not yet proven if testosterone was the culprit of the clotting and if stopping the treatment would have the desired effect.
The study involved an examination of around 19,000 health data about cases of blood clots and over 900,000 men without a history of blood clotting gathered from 2001 to 2003 in the United Kingdom. Three groups were examined in the research including those currently receiving treatment, patients who recently received treatment and those who have no treatment history for the past two years. Patients who receive current treatment were subcategorized, according to duration of therapy.
In a similar research conducted by Dr. Joao Zambon, he suggested that there is a possible link between cardiovascular diseases and blood clots with low testosterone intake. However, he said that "it is unclear if this is a causal relationship or a concomitant event." He added that "there are still many controversies and questions" about testosterone treatment despite its contribution to improving quality of life.
Testosterone is currently prescribed to address sexual dysfunction, reduced libido, mood disorders, reduced muscle mass, bone mineral density, and fatigue.
